Harness adds +5.3 points to DeepSeek V4.1 Flash on F1 pit-stop test, at ~19x the cost
AccBalanced · x · 2026-11-09
LatentOperatorX ran a controlled F1 pit-stop test: same DeepSeek V4.1 Flash Fast, same provider (Command Code), same prompt, high effort.
With the DeepSeek harness: 7.9/10 score, 73 minutes, $0.93, 264k tokens. Without: 2.6/10, 8 minutes, $0.05, 86k tokens. The harness delivers +5.3 points at roughly 19x the cost — the author asks whether that trade is worth it.
